Summary:
Grey Sloan Memorial Hospital enters crisis mode as the storm rages,
resources become scarce and patients flood in by the busload. Meanwhile,
one of the doctors fights for their life.

The doctors of Seattle
Grace Hospital deal with life-or-death consequences on a daily basis -
it's in one another that they find comfort, friendship and, at times,
more than friendship. Meredith's (Ellen Pompeo), along with interns
Cristina Yang, Izzie Stevens, George O'Malley and Alex Karev's, medical
world revolved around textbooks and professors yesterday, but today they
are experiencing medicine first-hand as surgical interns at Seattle
Grace Hospital, a teaching hospital with one of the toughest residency
programs in the nation. Here, they must learn to balance their personal
lives with their highly competitive professional lives, all while
dealing with the daily stress of life and death situations. Together
they're discovering that neither medicine nor relationships can be
defined in black and white. Real life only comes in shades of grey.
